FIELD

Various embodiments of the disclosure relate to emergency alertmessages. More specifically, various embodiments of the disclosurerelate to an electronic device and method for emergency alert messagedetection based on audio-video information.

BACKGROUND

Advancements in electronics and communication technology have led todevelopment of various techniques to detect and render emergency alertmessages on electronic devices, such as, televisions. Typically, anemergency alert message may be communicated over a pre-determinedbroadcast channel to an electronic device (for example, a television)that may receive multiple broadcast channels. On detection of theemergency alert message at a service provider device associated with theelectronic device, the service provider device (i.e., a broadcasterdevice) may switch a signal that may be broadcasted to the electronicdevice with the emergency alert message. Based on the switch of thebroadcasted signal to the emergency alert message at the serviceprovider device, the electronic device may receive and render theemergency alert message. However, the switch of the broadcasted signalto the emergency alert message at the service provider device may beabrupt and may impact a user experience of a viewer of the television.In certain cases, the emergency alert message may not be relevant to theviewer, and the viewer may choose to ignore the emergency alert message.In such cases, the switch of the broadcasted signal may be unnecessary.In addition, in certain scenarios, the viewer may be interested to viewor may be viewing non-broadcast content through the electronic device.For example, the electronic device may be used to view the non-broadcastcontent either stored on a media storage device associated with theelectronic device or received via an internet or via an over-the-top(OTT) platform. In such cases, the emergency alert messages may not bedelivered to the electronic device, as the electronic device may not betuned-in to any broadcast channel broadcasted by the service providerdevice. At the time of an emergency, the emergency alert messages may bemissed by the electronic device which may further impact the viewer atan extent.

Limitations and disadvantages of conventional and traditional approacheswill become apparent to one of skill in the art, through comparison ofdescribed systems with some aspects of the present disclosure, as setforth in the remainder of the present application and with reference tothe drawings.

DETAILED DESCRIPTION

The following described implementation may be found in the disclosedelectronic device and method for emergency alert message detection onthe electronic device based on audio-video information. Exemplaryaspects of the disclosure provide an electronic device (for example, atelevision (TV), a display device, a mobile phone, or a sound system)that may detect an emergency alert message based on audio-videoinformation. The electronic device may be configured to receive firstmedia content over a first broadcast channel. As an example, the firstmedia content may correspond to over-the-air (OTA) media content,television (TV) broadcast content, satellite TV content, or cable TVcontent. The electronic device may be further configured to control adisplay device associated with the electronic device to render secondmedia content. The second media content may be different from the firstmedia content. As an example, the second media content may correspond toone of over-the-top (OTT) media content, streaming media content, mediacontent stored on the electronic device, or media content received froman Internet.

The electronic device may be further configured to detect, from thereceived first media content, a set of objects (for example, but is notlimited to, an individual, a podium, a desk, a flag, or an emblem)associated with a geo-location corresponding to the electronic device.In an embodiment, the set of objects may correspond to an emergency(e.g., a natural calamity, a pandemic, an earthquake, a flood, atornado, or a war) at the geo-location. The electronic device may befurther configured to detect an emergency alert audio in the receivedfirst media content. The electronic device may be further configured toextract an emergency alert message received over a second broadcastchannel associated with the geo-location based on the detected set ofobjects and the detected emergency alert audio in the received firstmedia content. Thereafter, the electronic device may be configured tocontrol an output of an emergency alert signal, associated with theextracted emergency alert message. As an example, the emergency alertsignal may include at least one of audio content, video content, or textcontent.

In one scenario, the electronic device may output the emergency alertsignal in a single-view mode, such that the audio content, the videocontent, and/or the text content associated with or included in theemergency alert signal may be output concurrently. In another scenario,the electronic device may output the emergency alert signal and thesecond media content in a composite-view mode, such that the audiocontent associated with the emergency alert signal and video contentassociated with the second media content may be output concurrently. Inyet another scenario, the electronic device may output the emergencyalert signal and the second media content in the composite-view mode,such that the video content and/or the text content associated with theemergency alert signal and audio content associated with the secondmedia content may be output concurrently.

Typically, emergency alert messages may be communicated overpre-determined broadcast channels and may be detected at serviceprovider devices. On detection of an emergency alert message, theservice provider device may switch a broadcast channel (i.e., that maybe currently tuned on a television device) with the pre-determinedbroadcast channel associated with the emergency alert message. Once thetelevision device is tuned to the pre-determined broadcast channelassociated with the emergency alert message, the television device mayrender the emergency alert message. However, the switch to thepre-determined broadcast channel based on the detection of the emergencyalert message at the service provider device may be abrupt and mayimpact a viewing experience of a viewer of the television device. Inmany cases, the emergency alert message may not be relevant to theviewer, and viewer may choose to ignore the emergency alert message. Forexample, the emergency alert message may be related to a geo-locationthat may not be associated with the viewer and/or the television device.In such cases, the switch to the pre-determined broadcast channel may beunnecessary. Further, in case the television device is not tuned to anybroadcast channel and renders non-broadcast content (such as, streamingcontent, OTT content, or content stored on a media storage device (likea universal serial bus (USB) drive, a compact disc, a Solid-State Driveor a secure digital card)), the television device may be unable toreceive the emergency alert message (i.e. related to an emergency) fromthe service provider device, which may further impact the viewer.

In contrast, the disclosed electronic device may extract the emergencyalert message from an emergency broadcast channel based on the set ofobjects (e.g., an individual, a podium, a desk, a flag, or an emblem)automatically detected from another broadcast channel, at the time aviewer of the electronic device may be watching or listening to contentrelated to the non-broadcast content (for example an OTT content). Theset of objects may be associated with the geo-location (e.g., a locationwhere the viewer resides) associated with the electronic device. The setof objects may correspond to an emergency (e.g., a natural calamity, adisease (such as, a pandemic), or a war) at the geo-location. As the setof objects may be related to the emergency at the geo-locationassociated with the viewer, the emergency alert message extracted basedon the detected set of objects may be relevant to the viewer. Further,the electronic device may detect the emergency alert audio in thereceived first media content (i.e., received via a broadcast channel) tocorroborate whether the detected set of objects correspond to theemergency. The disclosed electronic device may extract the emergencyalert message based on the automatic detection of the set of objects andthe detection of the emergency alert audio in the first media content,when the viewer may not be rendering content from the broadcast channelor rendering the non-broadcast content (for example the OTT content).Therefore, the disclosed electronic device ensures that the viewer maynot miss any important emergency alert message (i.e., received on thebroadcast channel), even in a case when the non-broadcast content isbeing rendered to the viewer.

The disclosed electronic device may output the extracted emergency alertmessage in a single-view mode in which the audio, video, and textcontent of the emergency alert message may be output. Alternatively, theelectronic device may output the extracted emergency alert message in acomposite-view mode. In one scenario of the composite-view mode, theaudio content of the emergency alert message may be output concurrentlywith the video content of the second media content (i.e., non-broadcastcontent). In another scenario of the composite-view mode, the videocontent and/or the text content of the emergency alert message may beoutput concurrently with the audio content of the second media content.Thus, the disclosed electronic device may enable the viewer to view andlisten to the emergency alert message attentively in the singleview-mode in case the emergency alert message is important to viewer.Alternatively, the disclosed electronic device may enable the viewer tolisten to the audio of the emergency alert message and continue to watchthe second media content or watch/read the emergency alert message andcontinue to listen to the second media content. Herein, the emergencyalert message may be delivered to the viewer and further consumed by theviewer in the background while the viewer continues to consume thesecond media content (i.e., non-broadcast content). Thus, the experienceof the viewer may be enhanced as the viewer may not be disturbed by theabrupt channel switch on the detection of the emergency alert message.

The operations may include reception of the first mediacontent 104A, control of the display device 112 to render the secondmedia content 106A, detection of the set of objects, detection of theemergency alert audio, extraction of the emergency alert message, andcontrol of an output of the emergency alert signal. The circuitry 202may include one or more processing units, which may be implemented as aseparate processor. In an embodiment, the one or more processing unitsmay be implemented as an integrated processor or a cluster of processorsthat perform the functions of the one or more specialized processingunits, collectively. The circuitry 202 may be implemented based on anumber of processor technologies known in the art.

Examples ofimplementation of the memory 204 may include, but are not limited to,Random Access Memory (RAM), Read Only Memory (ROM), ElectricallyErasable Programmable Read-Only Memory (EEPROM), Hard Disk Drive (HDD),a Solid-State Drive (SSD), a CPU cache, and/or a Secure Digital (SD)card.

The ML model 212 may be trained on a task to detect the set of objects(that may correspond to a geo-location) from the first media content(that may be received over the first broadcast channel). For example,the ML model 212 may be trained to analyze the received first mediacontent to detect a flag, a podium, an emblem, a political figure, aneminent personality, or a government official (or any visual object thatmay correspond to an emergency) associated with the geo-location of theelectronic device 102. In an embodiment, the ML model 212 may be traineddetermine a discontinuity in input media content based on a set of audiosamples related to an emergency alert audio in the input media content.In an embodiment, the ML model 212 may be trained to convert audiosamples in input media content to corresponding textual information. Incertain scenarios, the ML model 212 may be implemented as a combinationof ML models including at least one of a first ML model trained todetect the set of objects, a second ML model trained to determine thediscontinuity in input media content, and/or a third ML model trained toconvert audio samples in input media content to corresponding textualinformation.

For example, the deep learning model may be adeep neural network-based model that may have a number of nodes (orneurons), activation function(s), number of weights, a cost function, aregularization function, an input size, a learning rate, number oflayers, and the like. Such a model may be referred to as a computationalnetwork or a system of nodes (for example, artificial neurons). For adeep learning implementation, the nodes of the deep learning model maybe arranged in layers, as defined in a neural network topology. Thelayers may include an input layer, one or more hidden layers, and anoutput layer. Each layer may include one or more nodes (or artificialneurons, represented by circles, for example). Outputs of all nodes inthe input layer may be coupled to at least one node of hidden layer(s).Similarly, inputs of each hidden layer may be coupled to outputs of atleast one node in other layers of the model. Outputs of each hiddenlayer may be coupled to inputs of at least one node in other layers ofthe deep learning model. Node(s) in the final layer may receive inputsfrom at least one hidden layer to output a result. The number of layersand the number of nodes in each layer may be determined from thehyper-parameters, which may be set before, while, or after training thedeep learning model on a training dataset.

Each node of the deep learning model may correspond to a mathematicalfunction (e.g., a sigmoid function or a rectified linear unit) with aset of parameters, tunable during training of the model. The set ofparameters may include, for example, a weight parameter, aregularization parameter, and the like. Each node may use themathematical function to compute an output based on one or more inputsfrom nodes in other layer(s) (e.g., previous layer(s)) of the deeplearning model. All or some of the nodes of the deep learning model maycorrespond to same or a different mathematical function. In training ofthe deep learning model, one or more parameters of each node may beupdated based on whether an output of the final layer for a given input(from the training dataset) matches a correct result based on a lossfunction for the deep learning model. The above process may be repeatedfor same or a different input until a minima of loss function isachieved, and a training error is minimized. Several methods fortraining are known in the art, for example, gradient descent, stochasticgradient descent, batch gradient descent, gradient boost,meta-heuristics, and the like.

Further, theelectronic device 102 may receive (via the I/O device 208) a user inputindicative of information related to the second media content 106A (forexample, a non-broadcast content, such as a video stored in the memory204). For example, the information related to the second media content106A may include a file name and a storage location path associated withthe second media content 106A. Alternatively, in case the second mediacontent 106A is OTT media content, the information may include logincredentials of an OTT media platform that hosts the OTT media contentand a name of the OTT media content. In an example, the electronicdevice 102 may display (via the display device 112 associated with theI/O device 208) the detected emergency alert message, the first mediacontent 104A, and the second media content 106A. Examples of the I/Odevice 208 may include, but are not limited to, a touch screen, akeyboard, a mouse, a joystick, a display device (for example, thedisplay device 112), a microphone, or a speaker.

Various operationsof the circuitry 202 for emergency alert message detection and renderingon the electronic device 102 are described further, for example, inFIGS. 3A, 3B, 4A, 4B, 4C, 5A, 5B, 5C, and 6 .

FIGS. 3A and 3B, collectively depict a diagram that illustrates anexemplary processing pipeline for emergency alert message detection onan electronic device based on audio-video information, in accordancewith an embodiment of the disclosure. FIGS. 3A and 3B are explained inconjunction with elements from FIG. 1 and FIG. 2 . With reference toFIGS. 3A and 3B, there is shown an exemplary processing pipeline 300that illustrates exemplary operations from 302 to 312 for detection ofemergency alert message on the electronic device 102 based onaudio-video information. The exemplary operations may be executed by anycomputing system, for example, by the electronic device 102 of FIG. 1 orby the circuitry 202 of FIG. 2 .

At 302, the first media content 104A may be received. In an embodiment,the circuitry 202 may be configured to receive a first media content(e.g., a first media content 302A) over a first broadcast channel. Priorto the reception of the first media content 302A, the circuitry 202 maybe configured to receive a user input, that may include an instructionto turn on the electronic device 102 and tune to the first broadcastchannel. The circuitry 202 may be configured to receive the user input,via the I/O device 208 associated with the electronic device 102. Basedon the received user input, the circuitry 202 may be configured to turnon and scan a set of broadcast channels as per a geo-location of theelectronic device 102. The circuitry 202 may be configured to determinea geographical region including the geo-location associated with theelectronic device 102. The determination of the geo-location associatedwith the electronic device 102 is described further, for example, inFIG. 1 . The set of broadcast channels associated with the determinedgeographical region may be received from a service provider device (notshown) associated with a service provider. The service provider devicemay use standard broadcasting protocols or common channel broadcastingprotocols to broadcast the set of broadcast channels to electronicdevices associated with the geographic region. The geographical regionmay correspond to an area of a city, state, province, or a country towhich the electronic device 102 may belong or located.

In an embodiment, to receive the first media content 302A, the circuitry202 may be configured to tune into the first broadcast channel of theset of broadcast channels, via a tuner or a frequency scanner (notshown) in the electronic device 102. The tuner or frequency scanner maybe configured to tune a broadcast channel frequency of the selectedfirst broadcast channel to receive a signal (related to the first mediacontent 302A) communicated on the selected first broadcast channel. Thetuner or the frequency scanner may amplify the received signal of theselected first broadcast channel, and further demodulate the amplifiedsignal of the selected first broadcast channel on the electronic device102, to further receive the first media content 302A. A detaileddescription for the other components or systems of the electronic device102 is omitted from the disclosure for the sake of brevity. In FIG. 3A,there is shown, an exemplary image frame of the first media content 302Athat may be received by the electronic device 102.

In an embodiment, the first media content 302A may correspond to one of,but not limited to, over-the-air (OTA) media content, television (TV)broadcast content, satellite TV content, or cable TV content. Forexample, the OTA media content may correspond to media content receivedover a first OTA channel associated with a particular OTA frequency. Thecircuitry 202 may render the OTA media content that may be aired orbroadcast on the particular OTA frequency. The TV broadcast content maycorrespond to media content received over a first TV broadcast channel.Examples of the TV broadcast channel may include, but are not limitedto, a National Television System Committee (NTSC) channel, an AdvancedTelevision System Committee (ATSC) channel, a Digital Video Broadcast(DVB) channel, an Integrated Services Digital Broadcast (ISDB) channel,or a Digital Terrestrial Multimedia Broadcast (DTMB) channel. Thesatellite content may correspond to media content received over a firstsatellite broadcast channel, for example, but not limited to, a directbroadcast satellite (DBS) service, and direct-to-home (DTH) satelliteservice. The cable TV content may correspond to media content receivedover a first cable TV channel associated with a particular RF frequencysignal transmitted via coaxial cables or fiber-optic cables.

At 304, the second media content 106A may be rendered. In an embodiment,the circuitry 202 may be configured to control the display device 112 torender a second media content (e.g., a second media content 304A).Herein, the second media content 304A may be different from the firstmedia content 302A received over the first broadcast channel. In anembodiment, the second media content 304A may correspond to one of, butnot limited to, an over-the-top (OTT) media content, streaming mediacontent, media content stored on the electronic device 102, or mediacontent received from the second AV server 106 or an Internet. Forexample, the OTT media content may correspond to media content receivedover a first OTT media service/platform via the Internet. The circuitry202 may render the OTT media content (via the display device 112) thatmay be received from a particular OTT media service. The streaming mediacontent may correspond to media content received over a streamingservice. The media content stored on the electronic device 102 maycorrespond to a pre-recorded or media content stored on the memory 204(or on any external storage device, such as a USB device, a compact disc(CD), solid-state device, and like) associated or directly coupled withthe electronic device 102. The circuitry 202 may be configured toretrieve the media content stored on the electronic device 102 andrender the retrieved media content (via the display device 112).Alternatively, the media content may be received from the second AVserver 106 or an Internet. Such media content be any live orpre-recorded media content received from the second AV server 106 or theInternet. In FIG. 3A, there is shown, an exemplary image frame of thesecond media content 304A that may be rendered on the display device112. In an exemplary scenario, where the second media content 304A (suchas OTT media content) is rendered via the display device 112 (as per apreference of the viewer/listener of the electronic device 102), thereceived first media content 302A (i.e., broadcast media content) maynot be rendered (via the display device 112 or via any other outputdevice) at the same time. In other words, the viewer of the electronicdevice 102 might be watching the OTT content (i.e., the second mediacontent 304A), but not watching the first media content 302A (i.e.,received over the first broadcast) at the same time (i.e., for examplein a composite-view mode, where two different media contents may beviewed at same time). Thus, in such case, the viewer may miss theemergency alert message broadcasted over a second broadcast channeland/or the first broadcast channel. Therefore, the disclosed electronicdevice 102 may automatically detect the set of objects and/or theemergency alert audio (i.e., corresponding to the emergency) from thereceived first media content 302A (i.e., even if the viewer may bewatching the second media content 304A), and accordingly extract theemergency alert message from the second broadcast channel based on thedetection, as further described, in FIG. 3 (at 306-312).

At 306, a set of objects may be detected. In an embodiment, thecircuitry 202 may be configured to detect, from the received first mediacontent 302A, the set of objects (e.g., a set of objects 306A)associated with the geo-location corresponding to the electronic device102. For example, the set of objects 306A may include, but are notlimited to, one or more individuals, a podium, a desk, a flag, or anemblem, associated with the geo-location corresponding to the electronicdevice 102. In an embodiment, the set of objects may correspond to anemergency (e.g., a natural calamity (such as earthquake, tornado,flood), a disease (such as pandemic), or a war) at the geo-location ofthe electronic device 102. As an example, the one or more individualsmay correspond to state or local authorities, a head of a state, city,or country, a broadcaster, or news anchor.

In an embodiment, the circuitry 202 may be configured to apply a machinelearning model (e.g., the ML model 212) on a set of image frames in thereceived first media content 302A. The machine learning model (e.g., theML model 212) may be trained on an object detection task to detect theset of objects 306A from the first media content 302A. For example, atraining dataset of the ML model 212 may include multiple frames of aplurality of media content and object tags associated with objectsincluded in each of the plurality of media content. The objects may bepre-determined for one or more geo-locations of a geographical region.In an embodiment, the ML model 212 may be based on one or more computervision models. The circuitry 202 may be configured to detect the set ofobjects 306A from the received first media content 302A based on theapplication of the ML model 212 (e.g., the one or more computer visionmodels) on the set of image frames in the first media content 302A.

In certain cases, the ML model 212 may detect one or more objects thatmay be similar to the set of objects 306A, from a group of image framesof the first media content 302A. However, the detected one or moreobjects may not be related to an emergency. For example, the ML model212 may detect a podium, a desk, or a commentator of a sports eventbroadcast (e.g., a soccer match), a flag associated with a sports team(e.g., a soccer team), and an emblem or flag associated with a countryassociated with the sports team. In such case, the circuitry 202 maydetermine that though the detected one or more objects are similar tothe set of objects 306A, the detected one or more objects may not berelated to an emergency. The detected one or more objects may be howeverrelated to the sports event. The circuitry 202 may ignore the group ofimage frames, that include the detected one or more objects, for thedetection of the set of objects 306A related to the emergency. In anembodiment, the circuitry 202 may re-train the ML model 212 to ignorethe detected one or more objects for the object detection task to detectthe set of objects 306A from the first media content 302A.

In an embodiment, the circuitry 202 may be configured to apply a machinelearning model (e.g., the ML model 212) on a set of audio samples in thereceived first media content 302A to determine textual content relatedto the set of audio samples. The machine learning model (e.g., the MLmodel 212) may be trained to convert audio samples to correspondingtextual information. For example, the ML model 212 may be aspeech-to-text or an audio-to-text converter that may be based on alanguage model. In an embodiment, the circuitry 202 may be configured todetermine a context associated with the determined textual content basedon the geo-location associated with the electronic device 102. Forexample, the ML model 212 may apply one or more natural languageprocessing (NLP) techniques on the determined textual content and on thegeo-location to determine the context associated with the determinedtextual content of the set of audio samples associated with the set ofimage frames in the received first media content 302A. The set of audiosamples may correspond to a dialogue, or a speech spoken or producedduring the capture of the set of image frames in the received firstmedia content 302A. For example, certain language slangs or idioms maybe associated with a particular context (like emergency) for aparticular geo-location. The use of such language slangs or idioms incase for the particular geo-location may indicate that the textualcontent may correspond to the particular context. For example, the MLmodel 212 may apply a language model specific to the geo-locationassociated with the electronic device 102 to determine the textualcontext of the determined textual content. In an embodiment, thecircuitry 202 may be configured to detect the set of objects 306A fromthe received first media content 302A further based on the determinedcontext. For example, in case the determined context corresponds to a“weather alert”, a set of objects (such as, a map with an indication ofheavy rains or storm) may be detected based on the determined context.In another example, in case of an accident, imminent danger, or naturaldisaster (e.g., storms, tornados, earthquakes), objects related to theemergency may be determined based on the textual context including wordssuch as, “emergency”, “high-alert”, “red-alert”, “warning”, “mayday”,“calamity”, “earthquake”, or “accident”. The audio samples in the firstmedia content 302A may be useful to corroborate whether the set ofobjects 306A are related to an emergency or not. For example, thetextual context determined from audio samples of the first media content302A indicates that the audio samples correspond to the set of objects306A. In such case, if the analysis of the image frames corresponding tothe same audio samples also leads to the detection of the set of objects306A, there is a high probability that the detected set of objectsrelate to an emergency. Thus, the analysis of the audio samples (todetermine textual context and associated textual context) may help toaccurately determine whether the detected set of objects corresponds toan emergency situation or not for the geo-location of the electronicdevice 102.

In an embodiment, the circuitry 202 may be configured to determine thegeo-location corresponding to the electronic device 102 based on atleast one of a user input or the location sensor 206 associated with theelectronic device 102, as described, for example, in FIG. 1 . Based onthe determined geo-location, the circuitry 202 may be further configuredto determine a second broadcast channel from a plurality of broadcastchannels received by the electronic device 102. The second broadcastchannel may be associated with (or available in) the geo-location,corresponding to which an emergency alert signal (e.g., the emergencyalert signal 108A) may be received by the electronic device 102. Forexample, the geo-location corresponding to the electronic device 102 maybe at a border area between two geo-graphical regions (e.g., twoneighboring states of a country). In such case, the emergency alertsignal 108A associated with both the states may be received by theelectronic device 102. The user of the electronic device 102 may beinterested in broadcast channels and emergency alert messages associatedwith the user's state. The disclosed electronic device 102 may determinethe second broadcast channel from the plurality of broadcast channelsreceived by the electronic device 102, based on the determinedgeo-location. Based on the determination of the second broadcast channelfrom the plurality of broadcast channels, emergency alert messagesassociated with the geo-location of the user may be received by theelectronic device 102. Example content rendering scenarios associatedwith the detection of the set of objects 306A, are described, forexample, in FIGS. 4A, 4B, and 4C.

At 308, an emergency alert audio 308A may be detected. In an embodiment,the circuitry 202 may be configured to detect the emergency alert audio308A in the received first media content 302A. The emergency alert audio308A may correspond to a predetermined audio signal (e.g., an audiotone) that may be used to alert users (for example, viewers of theelectronic device 102) of an upcoming alert message related to anemergency. In an example, the emergency alert audio 308A may correspondto a two-tone attention signal of 853 Hz and 960 HZ sine wave. Inanother example, the emergency alert audio 308A may correspond to a 1050Hz audio signal. In another embodiment, the emergency alert audio 308Amay correspond to the set of audio samples (i.e., dialogue or speech)related to the emergency,

At 310, an emergency alert message 310A may be extracted. In anembodiment, the circuitry 202 may be configured to extract the emergencyalert message received over the second broadcast channel (i.e.,associated with the geo-location) based on the detected set of objects306A and the detected emergency alert audio 308A. The emergency alertmessage 310A may include at least one of audio content, video content,or text content. For example, the emergency alert message 310A mayinclude a text such as, “Tornado warning in CA at 1300 hours tomorrow”.

In an embodiment, the circuitry 202 may be configured to determine adiscontinuity in the received first media content 302A based on thedetected set of objects 306A. For example, the received first mediacontent 302A may correspond to a soap opera or a theatre drama video. Incase the set of objects 306A, (such as, a podium and an emblem of acountry or a government agency) are detected from the received firstmedia content 104A, the circuitry 202 may determine a discontinuity inthe received first media content 302A or in current set of image frames,as the detected set of objects 306A may not correspond to the soap operaor the theatre drama video. In an embodiment, the circuitry 202 may usea machine learning model (e.g., the ML model 212) to determine thediscontinuity in the received first media content 302A based on thedetected set of objects 306A or based on context mismatch between thefirst media content 104A and the set of objects 306A. For contextmatching, the circuitry 202 may compare different information related tothe first media content 302A (like related to title, lyrics, dialogue,actors, genre, and the like) with the detected set of objects 306Acorresponding to the emergency. In case of significant mismatch betweenthe context of the first media content 302A and the detected set ofobjects 306A, the circuitry 202 may determine that the first mediacontent 302A (i.e., received over the first broadcast channel) is beingdiscontinued by the set of objects 306A being included in the firstmedia content 302A as received from the first AV server 104.

In an embodiment, the circuitry 202 may be configured to apply a machinelearning model (e.g., the ML model 212) on the set of audio samplesrelated to the emergency alert audio 308A in the received first mediacontent 302A. Further, the circuitry 202 may determine the discontinuityin the received first media content 302A based on the application of theML model 212 on the set of audio samples. For example, the ML model 212may be include an audio-to-text converter model and/or a naturallanguage processing (NLP) model. The ML model 212 may be configured toconvert, by use of the audio-to-text converter model, the set of audiosamples to corresponding textual information and further determine, byuse of the NLP model, one or more contexts associated with thecorresponding text information. Based on determined one or morecontexts, the ML model 212 may determine a discontinuity of contextbetween a first portion of text and a second portion of text in thetextual information. Based on the determined discontinuity of context,the circuitry 202 may be configured to determine the discontinuity inthe received first media content 302A using the set of audio samplesrelated to the emergency alert audio 308A. For example, the first mediacontent 302A may be related to a sports event and an initial textualcontext of the first media content 302A may be related to a commentaryof sports journalist who may analyze the progression of the game. Adiscontinuity may be detected, for example, when a textual context ofthe first media content 302A changes to a weather alert in the midst ofthe sports commentary. As the textual context of sports commentary maybe different from a weather alert, the circuitry 202 may indicate thechange in textual context as the discontinuity of context.

In an embodiment, the extraction of the emergency alert message 310A maybe further based on the determined discontinuity. For example, based onthe determined discontinuity, the circuitry 202 may further tune theelectronic device 102 to the second broadcast channel associated withthe geo-location. In other words, the circuitry 202 may switch thereception of signals/content from the first broadcast channel to thesecond broadcast channel (i.e., that may be including the emergencyalert message). The circuitry 202 may further extract the emergencyalert message 310A received over the second broadcast channel. In someembodiments, the emergency alert message 310A may be directly extractedfrom the first media content 302A. In such case, the switch between thefirst broadcast channel to the second broadcast channel may not berequired while rendering the second media content 304A received from thesecond AV server 106 (i.e., non-broadcast source) or from the memory204.

In an embodiment, the circuitry 202 may be configured to determine astatic display portion in the received first media content 302A based onthe detected set of objects 306A. For example, the first media content302A may be a sports event (such as, a soccer match as shown, forexample, in FIG. 3A) and the detected set of objects 306A may beenclosed inside a window (as shown in FIGS. 3A and 4A-4C) that may beincluded in one or more image frames of the first media content 302A,wherein the set of objects 306A may include (but not limited to) anemblem of a state or a country, a podium, and a head of the state orcountry, or a symbol/image related to the emergency. In such case, thewindow (including the set of objects 306A) inside the received firstmedia content 302A of the sports event (such as, a soccer match) may bea static display portion. A rate of change of pixel location of suchobjects in the static display portion (e.g., the window of the set ofobjects 306A) across image frames of the first media content 302A may beless than a certain threshold value (e.g., a rate of change of a certainnumber of pixels per frame). In an example, the circuitry 202 may applya machine learning model (e.g., the ML model 212) on the received firstmedia content 302A to determine the static display portion in thereceived first media content 302A. The ML model 212 may be trained on aset of frames of one or more videos including static and non-staticportions. In an embodiment, the extraction of the emergency alertmessage 310A may be further based on the determined static displayportion. For example, based on the determined static portion, thecircuitry 202 may tune the electronic device 102 to the second broadcastchannel associated with the geo-location and further extract theemergency alert message 310A received over the second broadcast channel.

At 312, the emergency alert signal 108A may be output. In an embodiment,the circuitry 202 may be configured to control the display device 112 tooutput the emergency alert signal 108A associated with the extractedemergency alert message 310A. In an embodiment, media content associatedwith the emergency alert signal 108A may include at least one of audiocontent, video content, or text content. The emergency alert signal 108Amay correspond to warning alerts for public that may be broadcasted viathe second broadcast channel (for example, a broadcast televisionchannel, a satellite television, a radio broadcast station, and a cabletelevision channel). For example, authorized officials associated withnational or local authorities may publicize the warning alertsassociated with emergencies. Such emergencies may include, and may notlimited to, civil emergencies, weather alerts, or any other emergencyalerts. For example, the emergencies may include, but are not limitedto, natural calamities, pandemic diseases, law-and-order issues, or war.

In an embodiment, the circuitry 202 may be configured to control thedisplay device 112 to render, in a single-view mode, the emergency alertsignal 108A that may be associated with the emergency alert message 310Areceived from the second broadcast channel. The render of the emergencyalert signal 108A in the single-view mode is described further, forexample, in FIG. 5A. In an embodiment, the circuitry 202 may beconfigured to control the electronic device 102 to switch from the firstbroadcast channel to the second broadcast channel, for the extraction ofthe emergency alert message 310A. In an embodiment, the circuitry 202may be configured to render the emergency alert signal 108A (i.e.,extracted from the second broadcast channel) along with the second mediacontent 304A in a composite-view mode. In an embodiment, in thecomposite-view mode, the circuitry 202 may be further configured tooutput audio content associated with the emergency alert signal 108A(i.e., extracted from the second broadcast channel) and concurrentlyoutput video content associated with the second media content 304A. Inanother embodiment, in the composite view-mode, the circuitry 202 may befurther configured to output at least one of text content or videocontent associated with the emergency alert signal 108A (i.e., extractedfrom the second broadcast channel) and concurrently output audio contentassociated with the second media content 304A. The output of theemergency alert signal 108A in the composite-view mode is describedfurther, for example, in FIGS. 5B and 5C. The concurrent output of theemergency alert signal 108A and the second media content 304A by thedisclosed electronic device 102 may ensure that the viewer may not missthe important emergency alert message 310A while watching the secondmedia content 304A (i.e., like OTT content received overnon-broadcasting channel) and may also have continuous experience of thesecond media content 304A (at least in a video or audio form). Further,a combination of image frame analysis (for the detection of set ofobjects 306A) and audio sample analysis (for the determination of thetextual context) may be performed from the broadcast content (i.e., thefirst media content 302A) by the disclosed electronic device 102. Hence,the detection of emergency notifications (and discontinuities) may bemore accurate compared to detection based on one of the set of objects306A or the set of audio samples in the first media content 302A.

In an embodiment, the circuitry 202 may be configured to monitor thesecond broadcast channel to detect the emergency alert audio 308A (orthe emergency alert message 310A), based on the electronic device 102being in an idle mode (or in sleep or standby mode). The circuitry 202may be further configured to control the output of the emergency alertsignal 108A associated with the extracted emergency alert message 310Abased on the monitored second broadcast channel. For example, in casethe electronic device 102 is in a standby mode, or if the electronicdevice 102 is not tuned to any other broadcast channel (like the firstbroadcast channel or the second broadcast channel), then the circuitry202 may be configured to monitor the second broadcast channelcontinuously for the emergency alert signal 108A. Based on theextraction of the emergency alert signal 108A, the electronic device 102may automatically switch to the second broadcast channel and output theemergency alert signal 108A associated with the emergency alert message310A.

FIGS. 5A, 5B, and 5C are diagrams that illustrate exemplary scenarios tooutput an emergency alert signal, in accordance with an embodiment ofthe disclosure. FIGS. 5A, 5B, and 5C are described in conjunction withelements from FIGS. 1, 2, 3A, 3B, 4A, 4B, and 4C. With reference to FIG.5A, there is shown an exemplary scenario 500A. The exemplary scenario500A may include the electronic device 102 that may include the displaydevice 112 and a speaker (not shown). In an embodiment, the circuitry202 may be configured to extract the emergency alert message 310Areceived over the second broadcast channel associated with thegeo-location of the electronic device 102. Herein, the extraction of theemergency alert message 310A may be based on the detected set of objects306A and the detected emergency alert audio 308A in the received firstmedia content 104A. The extraction of the emergency alert message 310Ais described further, for example, in FIGS. 3A and 3B. In an embodiment,the circuitry 202 may be configured to control the display device 112 torender, in a single-view mode, the emergency alert signal 108A that maybe associated with the emergency alert message 310A received from thesecond broadcast channel. For example, audio content of the emergencyalert signal 108A associated with an emergency alert message 502 may beoutput through the speaker associated with the electronic device 102.Further, video content or text content of the emergency alert signal108A associated with the emergency alert message 502 may be displayed onthe display device 112 associated with the electronic device 102. Asshown in FIG. 5A, the emergency alert message 502 may correspond to a“Tornado Warning”.

With reference to FIGS. 5B and 5C, there are shown exemplary scenarios500B and 500C. The exemplary scenarios 500B and 500C may include theelectronic device 102 that may include the display device 112 and aspeaker (not shown). In an embodiment, the circuitry 202 may beconfigured to control the electronic device 102 to switch from the firstbroadcast channel to the second broadcast channel, for the extraction ofthe emergency alert message 502. The circuitry 202 may be configured torender the emergency alert signal 108A from the second broadcast channelalong with the second media content 106A in a composite-view mode. Forexample, as shown in FIG. 5B, in the composite-view mode, the emergencyalert signal 108A and the second media content 106A may be renderedconcurrently in a side-by-side configuration on the display device 112.In another example, as shown in FIG. 5C, in the composite-view mode, theemergency alert signal 108A and the second media content 106A may berendered concurrently in a picture-in-picture configuration on thedisplay device 112.

In an embodiment, in the composite-view mode, the circuitry 202 may befurther configured to output audio content (i.e., like warning audiomessage) associated with the emergency alert signal 108A andconcurrently output video content associated with the second mediacontent 106A. In another embodiment, in the composite view-mode, thecircuitry 202 may be further configured to output at least one of textcontent or video content (i.e., warning text or video message)associated with the emergency alert signal 108A and concurrently outputaudio content associated with the second media content 106A. Theconcurrent output of the emergency alert signal 108A and the secondmedia content 106A by the disclosed electronic device 102 may ensurethat the viewer may not miss the important emergency alert message 502while watching the second media content 106A (i.e., like OTT contentreceived over non-broadcasting channel) and may also have continuousexperience of the second media content 106A (at least in a video oraudio form)

Typically, emergency alert messages may be communicated overpre-determined broadcast channels and may be detected at serviceprovider devices. On detection of an emergency alert message, theservice provider device may switch a broadcast channel (i.e., that maybe currently tuned on a television device) with the pre-determinedbroadcast channel associated with the emergency alert message. Once thetelevision device is tuned to the pre-determined broadcast channelassociated with the emergency alert message, the television device mayrender the emergency alert message. However, the switch to thepre-determined broadcast channel based on the detection of the emergencyalert message at the service provider device may be abrupt and mayimpact a viewing experience of a viewer of the television device. Inmany cases, the emergency alert message may not be relevant to theviewer, and viewer may choose to ignore the emergency alert message. Forexample, the emergency alert message may be related to a geo-locationthat may not be associated with the viewer and/or the television device.In such cases, the switch to the pre-determined broadcast channel may beunnecessary. Further, in case the television device is not tuned to anybroadcast channel and renders non-broadcast content (such as, streamingcontent, OTT content, or content stored on a local media storagedevice), the television device may be unable to receive the emergencyalert message (i.e., related to an emergency) from the service providerdevice, which may further impact the viewer.

In contrast, the disclosed electronic device 102 may extract theemergency alert message from an emergency broadcast channel (or from thereceived first media content 104A) based on the set of objects (e.g., anindividual, a podium, a desk, a flag, an emblem, or any visual objectrelated to the emergency) automatically detected from another broadcastchannel, at the time a viewer of the electronic device 102 may bewatching or listening to content related to the non-broadcast content(for example an OTT content). The set of objects may be associated withthe geo-location (e.g., a location where the viewer resides) associatedwith the electronic device 102. The set of objects may correspond to anemergency (e.g., a natural calamity, a disease (such as, a pandemic), ora war) at the geo-location. As the set of objects may be related to theemergency at the geo-location associated with the viewer, the emergencyalert message extracted based on the detected set of objects may berelevant to the viewer. Further, the electronic device 102 may detectthe set of audio samples (i.e., related emergency alert audio) in thereceived first media content 104A (in addition to the detection of theset of objects 306A) to accurately corroborate whether the detected setof objects correspond to the emergency or not. The disclosed electronicdevice 102 may extract the emergency alert message based on theautomatic detection of set of objects and the detection of the emergencyalert audio in the first media content, especially when the viewer maynot be rendering content from the broadcast channel or rendering thenon-broadcast content (for example the OTT content). Therefore, thedisclosed electronic device 102 ensures that the viewer may not miss anyimportant emergency alert message (i.e., received on the broadcastchannel), even in a case when the non-broadcast content (like OTTcontent) is being rendered to the viewer.

The disclosed electronic device 102 may further output the extractedemergency alert message in a single-view mode in which the audio, video,and text content of the emergency alert message may be output.Alternatively, the electronic device 102 may output the extractedemergency alert message in a composite-view mode. In one scenario of thecomposite-view mode, the audio content of the emergency alert messagemay be output concurrently with the video content of the second mediacontent 106A. In another scenario of the composite-view mode, the videocontent and/or the text content of the emergency alert message may beoutput concurrently with the audio content of the second media content106A. Thus, the disclosed electronic device 102 may enable the viewer toview and listen to the emergency alert message attentively in the singleview-mode in case the emergency alert message is important to him/her.Alternatively, the disclosed electronic device 102 may enable the viewerto listen to the audio of the emergency alert message and continue towatch the second media content 106A or watch/read the emergency alertmessage and continue to listen to the second media content 106A. Herein,the emergency alert message may be delivered to the viewer and furtherconsumed by the viewer in the background while the viewer continues toconsume the second media content 106A. Thus, by the disclosed electronicdevice 102, the experience of the viewer may be enhanced as the viewermay not be disturbed by the abrupt channel switch on the detection ofthe emergency alert message.
